Direct Fired / Once-Through Steam Generators (OTSG)
Meet the direct approach to steam generation.
We’ve been fabricating Once-Through Steam Generators since the early 1980s. That experience has built us a reputation in the industry, and it’s made many companies’ go-to solution.
In fact, we’ve designed, engineered, and manufactured about 95% of the OTSG units in operation across western Canada today.
Why OTSG
the preferred solution in Steam-Assisted Gravity Drainage & Cyclic Steam Service operations.
Once-Though Steam Generators (OTSG) are the preferred solution in Steam-Assisted Gravity Drainage (SAGD) and Cyclic Steam Service (CSS) operations due to several distinct advantages tailored to oilsands applications.
Modular Design
The larger the unit, the fewer total units are required to meet plant steam demand, but this often presents challenges for transportation. The modular design of our OTSGs allows for very large units to be shipped piecemeal, which not only facilitates easier transportation, but also quicker installation and scalability, making them ideal for remote oilfield locations.
Feedwater
Water goes in, and water comes out. The lack of steam drum and high-velocity flow inside the coils of an OTSG system mean that you’re less likely to deal with build up of contaminants and solids. This is vital if you’re working with recycled or brackish water as is often the case in SAGD operations for enhanced oil recovery.
Combustion
An OTSG relies on a burner fueled by natural gas, waste gas, or a combination to heat water into high-pressure steam. Burning produced, waste gas eliminates the need for site flaring activities. Current burner technology can easily meet emissions guidelines without the need for flue gas recirculation (FGR).
Are You Still unsure about Which type of steam generator Suits you best?
Customized equipment
We Customize Every System to Fit Your Exact Needs
Our customized designs mean that we can shape your order to your exact processes and technical requirements, maximizing the efficiency, safety, and longevity of your OTSG in a way that less experienced manufacturers will never be able to achieve.
Which is one of the reasons your project stays entirely in our hands. We design, purchase all materials, fabricate, ship to site, offload and install, field erect, and commission every OTSG system that we make.
So you can trust you’re fully benefiting from our experience and expertise every step of the way.
Why Choose Us
When our clients first come to us, it’s usually because they’ve heard we’re the best.
Either they’ve worked with us before and chose to return when establishing a new site, or they’ve realized that the solutions our competitors offered were more like additional problems.
Most companies can’t offer the level of customization that we do, and it’s rarely possible to hire the level of experience and expertise we’ve amassed over the decades, not only as a company with a long record of successful projects, but on a personal level—most of our staff bring decades of experience in their respective fields to our work.
Our competitors simply can’t provide the same quality of output or seamless integration into existing systems that we offer. And when their clients realize that, they become our clients.
The scale and importance of your steam generator means that you can’t afford to make mistakes in choosing its manufacturer. Which is why you’re better off with the experts in OTSG that have been trusted to build roughly 95% of the existing OTSG units currently operating in western Canada.
